SPECIFICATION forming part of Letters Patent No.355,625, dated January 1,,

Application filed July 11, 1884.

To all whom it may concern: Be it known that I, J OHN Srnvnrzs, of Port Byron, in the county of Cayuga, in the State of New York, have invented new and, useful. Improvements in Machines for Forming Vessels from laperPulp, of which the following is a specification. p

This invention relates to an improvement in that class of machines which are employed for forming the hollow bodies of paper vessels such as pails, barrels, 8tc.by winding-a web of soft paper stul't" 'upona suitable mandrel until a body having the desired thickness ha been deposited thereon.

The object of this invention is to improve the operation of this class of machines; and it consists in the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is Fig. 2 is a sectional side elevation thereof. Fig. 8 :is a detached front view of the pivoted support to which the formingmandrels are attached. Fig. 4 is .a perspective view of the removable metallic jacket.

. Like letters of reference refer to like parts in the several figures.

A represents the tank which receives the pulp.

Brepresenls the drum arranged in the tank A, and provided with perforated or reticulated peripheral wall in the usual manner.

0 represents a pump of any suitable eon- 'structiomwhercby the water is drawn from the interior of the depositing-drum B, thereby causing the paper-pulp to be deposited against the outer side of the drum. 7

D represents the coucher-roller covered with felt and arranged above the depositing-drum B, so as to-run in contact with the upper side thereof, and receiving the web of soft paper E represents a pressure roller bearing against the web of soft paper stulf on the aseending side of the coueher D,1"or the purpose of pressing any excess of moisture from the web.

F represents a clearing-roller bearing and removing any pbrtions of paper stud" 12s in Serial No. M53378. (No model.)

eoncher is covered.

f represents a scraper attached tea support, f, and bearing against the clearing-roller F, for the purpose of removing the paper-stuff from the roller F, which the. latter has taken from the concher;

9 represents a perforated pipe arranged above the contiguous portions of the rollers D and F and delivering a spray of water upon which may adhere to the felt with which the v the same, for the purpose of facilitating the removal of the shreds of-pa'per stufflfrom the coucherD. t.

'11" represent two forming-'mandrels mounted upon arborsh, which are-secured support,

with their rear ends .to atwoarm'ed I. The latter is secured to a shaft, 6, which is supported in bearings j.

J J are supports secured "at theirlower ends 17 to the tank A, and provided at their upper ends with bifurcated portions or parallel bars j, between which are arranged the hearingsj,

in, which the shaft 'i isjournaled. The upper ends of the bifurcated portionsjare connected by cap-pieces j", through which pass adj ustingscrews j, whereby the bearings can be raised and lowered between the bars j, in order to adjust the forming-inandrels -toward or from the eoueher. The arbor-s hare rigidly secured to the arms of the support I, and the mandrels H turn on said arbor-s. By turning the sup- 3' port I either of the mandrels II can bebrolight in contact with the coueher, so thatone of the mandrels can receive the so t't paper stuff from the coueher, while the complete body of paper-pulp is removedfroin the other mandrel and the latter again prepared for receiving another deposit of paper-pulp.

K represents jackets, constructed of zinc or other suitable metal, and adapted to be removablyapplied to the mandrcls H. The jackets K are divided lengthwise, and the contiguous longitudinal edges of each jacket are bent inwardly, forming-ribs k, which engagein a longitudinal groove-in the mandrel and hold the jacket against turning on the same.

L represents an elbow-lever, pivoted to the front side of the support J, below the pivoted support I, and bearing with its short aunt too against anose or projection, wafer-med at each end of the pivoted support, as, represented in I Fig. 3. The weight at the end of the long arm of the lever L tends to hold the lever inthe position in which it is represented in the drawings. p v As the thickness of the layer'of pulp on the I lower mandrel fl increases it. causes the sup port I- totn'tn on the shaft i in the direction of the. "arrowin, .Fig. weighted arm of the. lever 1 The-overlapping surfaces of the short a'rml'and nose m are made so long that the nose will disengage itself automatically from the short. arm Z when alayer of pulp of the required thiekness has 5 v .The weight causes the lever. L to return to its been: deposited upon the lower mandrel 1 'fornier position as soon as the .nnandr'el'has 'releaseditself from the lever, and the long'ar'm to the coucher D, and thence upon the lower I forminganandrel H, as indicated in'Fig.. 1.

The successive convolutions of'pulp are deposited upon the mandrel H until a body of "the required thickness has beenlfiorined, when the lower mandrel-disengages itself automatioally and severe the sott web of paper stuff. The npper mandrel, being previonsl y provided with metal'j'acket, K, is now swu'ng-downin contact with the ooucher D, and the web of paper stuff now passes around they lest-mendrum B, oouoher I), and i'orining-mandrels II,

I tinned mandrel, while the deposited body of paper stufl is removed from the first-named mandrel, together with the metal jacket upon which it was deposited. The. jacket is. re

moved from'the interior. of the-:eposit ed body of paper pulp by collapsing the jacket. In this manner-thewebof pap: Qtuff is alter- ..nately wouudupon the two mandiels, whereby hollow bodies of paper-pulp of uniform size and thickness are rapidly produced.

' v When the machine is used for forming the 3, thereby raising the;

bodies of paper pails, the depositing-drum B,

coue'her D, and forming mandrels- H are all lapered, as represented. in the drawings, oorre spending with'the taperoithe pail to be produced; but if a vesselof cylindrical form isv desired, all of these parts are made cylindricah I claim as my invention- 1'. The combination, with the pulp-deposit ing drun and couchemof interchangeable forming-mandrels mounted upon a-pivoted support-and a locking device, whereby the ivoi'ed support is held in positionnntil the vdesi'redthick nessof pul p has been wound upon I the mandrel, substantially as set forth.

The combination, with a pulp-depositing drum andeoueher, of interchangeable forniing-niandrels mounted upon. a pivoted supportend an automatic locking device which holds the pivoted support in position and releases th'e same automatically when the de-. sired thickness of pulp has been deposited 7 upon the'niandrel, substantially as set forth.
